## Description

Dive into this insightful panel from Pragma Istanbul 2023 as Ben Jones (Optimism), Jordi Baylina (Polygon zkEVM), and Alex Gluchowski (Matter Labs / zkSync) join ETHGlobal’s Kartik Talwar to break down the rollup landscape. They explore the evolution of L2s, why teams are launching their own chains, and how platforms like OP Stack, Polygon CDK, and zkStack compare on scalability, interoperability, and decentralization.

Hear direct insights on chain sovereignty, economic models, shared sequencing, proof aggregation, and the future of application-specific rollups. If you're building infrastructure or deploying onchain apps, this is a must-watch for understanding rollup strategy and the future of Ethereum scalability.

🇹🇷 *Pragma Istanbul*
The sixth edition of Pragma took place in Istanbul in November 2023 with a curated series of high-quality talks that sparked thought and discussion. Pragma Istanbul 2023 was an opportunity discuss the future of web3 and reflect on the past.
